  • Patent number: 5681226
    Abstract: A golf club shaft is described which has an upper grip portion with significantly greater diameter than the largest diameter of the lower power portion, with the two portions joined by an S-shaped transition portion. The large diameter of the grip portion permits recreational players or players with relatively weak hands to exert more power and greater control of the fine movements of the club shaft and golf club. The grip section has a minimum diameter at least 35% greater than the maximum diameter of the power section and the transition section has a length not greater than 15% of the overall length of the shaft. The shaft may be made of any convenient material which can be formed into the curves of the transition section without imposing undue stresses in the curved portions. The shaft may be formed of metal or, preferably, a fiber/polymer composite material.
